  1. I need to use the usb port from NA HMI to import and export a variable from NX102 to a CSV file. Anyone with a code solution for this? Thank you   
  2. Sample blocks for S7 1200 plc's

    Hi experts, please share the sample blocks for the EDITABLE TIMER block it should be editable from HMI(Siemens). And also motor run hour block. Actually i am having all blocks in tia v12 version and sadly i dont have the old software to convert it again. So please share the blocks that it shoud be work in TIA V14 for s7 1200 plc's. Please note that the blocks should use add instructions to calculate the time because i don't have much memory.
  3. I have a Modicon NOM0200 unit connected to an access switch to send commands to various rs-232 devices. The Access switch requires a "disconnect string" to end communication with a particular port. The disconnect string is "CRTL+D", how can I send a "CRTL" keystroke from the NOM0200 unit? I know for carriage return it is "$R" is their a similar combination I can enter for "CTRL"?  
  4. I can debug my plc app with simulator. I created some function block, and inside functionblock I can inspect in and out parameters, as well as local variables. But in/out parameters values are not shown. Any solution? Im using Sysmac Studio 1.29.2 and selected a NX PLC in my project.
  5. NB DESIGNER Number Input

    Hello,  I done connect HMI NB7W series to PLC CP1E and just using input and output (0,0 and 100,00) and i can send data from weighing scale to PLC CP1E with RS232 communication. My Question is, if i want to send data from HMI NB7W to PLC CP1E but must input the new data first using number input in HMI NB7W, can i send a new data with RS232 communication (like send data from weighing scale to PLC CP1E)? so i can save the new data to memory in CP1E. I use NB Designer Software and CX Programmer software. If possible, can you tell me how to do it?  Thank you Riandanu
  6. Hi everyone, Using Cicode programming ... I'm try to make a function empressed Button's input command that still running forever until the user press the Button again .. so if i press the Button at first the function inside Button will be running , But i wonder to terminate that function by press same button second time or don't mind if you suppose other Button for stop running the function ... plz help to make a code or something else to stop running of my function.
  7. Function Block addressing

    Hello all.  I have a program which has 8 function blocks. I recently added extra functionality to one of the programs (not the function blocks). I added the new variables to the global symbols table and added the new code, but when I compiled the new code, the variable addresses in three of the function blocks had changed. This is a problem, because we use memory cassettes to download new versions of code, so when the new version is downloaded to a machine in some far flung part of the world, these variables will be overwritten (they are hours run variable, so are important for servicing purposes).   My understanding is that CX assign's variable addresses in Function Blocks and we have no control over this. Bit if I only added variables to the Global symbol table, why are the FB addresses affected??   Any input appreciated. 
  8. Pointer Device memory

    To those who don't know the GX Works2 compiler treats any function block referenced used in your code as a place to copy the entire set of code data into your program. Function block calls are not handled like pointers even though the should be. [You'll consume all your pointer space by thinking function blocks are great.]
  9. Hey, I recently started trying my hand at creating function blocks. At the moment I'm trying to create a PID function block, however I keep getting this error: "ERROR: Variable does not have enough size." No idea why it does this. Can anyone help?  
  10. Hello! I am using S7-1200 PLC 1212C AC/DC with configured Modbus TCP Server. I can already read/write Inputs/Outputs (Coils) and Memory Words. However I'd like to read/write Memory BITS. Is it possible? If so, how? What addresses should I use in TIA portal? And which function codes on client side? Thanks in advance!
  11. Internal function block variables

    I have a function block where the first internal variable is showing as address H1420 in the Global Symbol table. When I add another retained variable to the function block then save and compile the code, the variable address in the global symbol table shifts from H1420 to H1488.  I need to retain the address as I will be downloading code and I need to ensure the address if H1420 stays with that variable.    Can anyone help with this?
  12. Omron Function Block variables

    Hello all.  I posted earlier in the week regarding downloading new code to an Omron PLC, but I think the question was a bit vague. As a follow up, and hopefully to clarify, I have the following query. I have created an upgraded program which will be downloaded by field techs using memory cassettes. The revised area of code is essentially a Function Block which amends service lamp behaviour, and in creating it, I have amended the existing function block and added new Internal variables. Is there any way I can ensure that the new variables don''t over write or move the existing  variables in the PLC, because this is what is happening when I download it.    HELP!!!!!!!!!
  13. hello.   I've been trying to communicate this omron plc CP1L-EM30DT1-D, with a yaskawa inverter cimr-vu4a0004faa. but i can't figure out how to make de correct mov or configuration in de DM. i need to run/stop, change frequency.    some help, please. :) 485PRUEBA.cxp 485PRUEBA.opt
  14. Not able to establish DDE connection

    Good day to all, I am trying to establish DDE communication between my PLC (1769-L23ER) and MS Access via RSLinx Classic Gateway (3.9) over Windows Server 2012 R2.  On my developing PC (Windows 7), there isn't any issue at all. But when I port the codes over to Windows Server 2012 R2, MS Access is not able to establish DDE communications with the PLC.  I was wondering what went wrong. The error message from MS Access is "MS Access can't find the specified application and topic because it can't open the DDE channel, err.Number is 282. The code for getting the channel is as follow OpenRSLinx = Application.DDEInitiate("RSLinx","PLC-D") I was wondering was there anything I have miss out. eg. Configuration of the server, path settings, etc.. Any help is welcome. TIA Cheers CY
  15. Hi, I have a a few substations and I´d like to have a local SCADA in each of them. What is the best scada to use with reasonable price? Does anyone know if there is a solution without the need to have a PC for each substation? Thanx
  16.

  17. Delta eserver problem

    Hi Guys, Im using delta eserver to get data from access and there is an error. How do you solve this? Eserver is installed on windows server 8  
  18. Hello:   I need to link  a lot of variables, pointing to CIO address, like "AT" field, but is a large volume of tags to create, so, I have a chance to assign a memory location to a variable in ST like:  my_tag := %100;  (trying to assign tag address to CIO 100) ? If not, there is a method to import tags from a Excel ?   Thanks.    
  19. Hello all. I have been working with an SLC 5/04 system, which houses various Digital and Analog INs and OUTs, up to Slot 29. I am currently mainly working with Slot 25, an Analog Input: 1746-NI16I. This is a system which has already been set up and has been running for the best part of 8-10 years. This particular card has had some spare inputs, one of which I am trying to connect to. In the Advanced Configuration, only a few Channels are actually "Enabled", and each channel is pretty much slightly different from another in terms of Input Type, Filter Frequency and Data Format. I am trying to set up Input 14, which is Channel 15, to "Enable" it, 4-20mA Input Type, Filter Frequency of 6 Hz and Data Format of either Raw/Proportional or Engineering Units. Now, after I have made my choices, I click apply, and then OK. I am then confronted by a pop-up which states: "Configuration Rung and Data Integer Data File Number: 25 Integer Data Element: 100 Rung to be inserted: XIC S2:1/15 COP #N25:100 #O0:25.0 24 At Program File Number: 4 82" I have the options of OK or Cancel. If I click OK, I now have LAD 4, Rung 82 Highlighted. This First Scan Bit and COP function were already here, but does that mean I have now altered what is being written to "#O:25.0"? I now Download the Changes. However, after all this, I am not getting any Analog input reading coming in from the Live PLC. What is this COP function? What does it do? How do I properly set up this Analog Card?   Thanks for your time, -Jame
  20. Was wondering if anyone can tell me whether it is possible to use the Red Lion Graphite displays to remotely log into your system via Ethernet for programming.  Can it be used as a bridge to other Ethernet devices connected to it?
  21. So I did this simple Function Block, pretty simple, and yet it keeps giving me this error, after a bunch of failed combinations the error persists, without telling me whats wrong. And therefore won't even allow me to download the program to the PLC (CJ2M CPU31) or even simulate.   I heard it's a simple thing to fix but I really dont know how to, since I'm quite new to this. Here's the function block  itself in the picture and the programming inside it, although since it gives me no errors, i don't think that would be the problem
  22. Block Compare Instruction

    Is there a Block Compare Instruction like the one in Omron PLC for Mitsubishi PLC? If the Omron PLC is BCMP (68), then what is the name of the instruction on the Mitsubishi PLC? I tried to use BKCMP in the Mitsubishi PLC, but the way it works is not the same as the one in Omron PLC
  23. Hello. How can I get bit addressing of defined variable in function block? For example: - I define variable type DUINT with name Double_VarI_INT. - I want to get or set one bit out of it (its double word). - If I use Double_VarI_INT.0 I got error. Best regards.
  24. Greetings, so i create project for FX3U in GX Works2. In my program i use function in ST. That function return array with word(signed). I have a warning: ST FOR i_var := 0 TO n_i BY 1 DO TempNumbs := Numbs; TempDevSetsOnPerTime := DevSetsOnPerTime; QueueBySetOn[i_var] := 0; END_FOR; QueueBySetOn[1] := TempNumbs[n_i]; QueueBySetOn[3] := 1; FOR i_var := 0 TO n_i BY 1 DO IF (TempDevSetsOnPerTime[TempNumbs[i_var]] < MaxSetsOnPerTime) THEN QueueBySetOn[0] := TempNumbs[i_var]; QueueBySetOn[3] := 0; EXIT; END_IF; END_FOR; So, it realy funny, GXW cant return int?
